Method of treating presbyopia with concentric bifocal contact lenses |
(57) Presbyopia is successfully alleviated in a person having binocular vision by a method
wherein a concentric bifocal contact lens having a central distant vision zone and
a peripheral near vision zone is fitted to one eye of the person and a second concentric
bifocal contact lens having a central near vision zone and a peripheral distant vision
is fitted to the other eye. The invention also comprises a kit containing a pair of
concentric contact lenses, one lens having a central vision zone adapted to correct
distant vision and a peripheral vision zone adapted to correct near vision, and the
other of said lenses having a central vision zone adapted to correct near vision and
a peripheral vision zone adapted to correct distant vision.
